94 Possible Causes for P Wave Absent

  • Ventricular Fibrillation

    Answers Rhythm: Irregular Rate: Unable to determine P Wave: absent PR interval: absent QRS: absent Interpretation: Ventricular Fibrillation (Fine) Lessons Overview Rhythm[] Answers Rhythm: Irregular Rate: Unable to determine P Wave: absent PR interval: absent QRS: absent Interpretation: Ventricular Fibrillation (Fine) Next Lesson » Table of Contents[]

  • Atrial Flutter

    Practice Strip Answers Rhythm: Regular Rate: Ventricles - 80, Atria - 320 P wave: "F" waves PR interval: absent QRS: 0.08 Interpretation: Atrial Flutter 4:1 Lessons Overview[] Sinus P waves are absent. The classic “sawtooth” pattern occurs, as the reentrant circuit around the tricuspid valve is large, resulting in high-amplitude P waves.[] With atrial flutter the 'P' waves are indeterminate. The PRI is indeterminate. Note the 'Flutter' or 'F' waves. They often look like a 'saw tooth' as well.[]

  • Sinus Arrest

    waves: Sinus P waves with basic rhythm; absent during pause PR interval: Normal (0.12 to 0.20 second) with basic rhythm; absent during pause QRS complex: Normal (0.10 second[] Occasionally and when the P waves are absent for a relatively long time, escape beats appear, as other groups of myocardial cells undertake the pacemaking process for a brief[] : inverted before or after the QRS, or absent PRI: not measurable if no P wave or if P wave occurs after QRS QRS: normal Wolff-Parkinson-White Syndrome (WPW) The short PR[]

  • Hyperkalemia

    Example of bradycardia with absent or flattened p waves in hyperkalemia. Care of Dr. Smith’s ECG blog.[] Peaked T waves. Example 5 Hyperkalaemia: Broad complex rhythm with atypical LBBB morphology. Left axis deviation. Absent P waves.[] Stabilize the cardiac membrane with Calcium Gluconate 1-3 amps ( or Calcium Chloride 1 amp if peri-arrest/arrest ) if: a) K 6.5 or b) wide QRS or c) absent p waves or d) peri-arrest[]

  • Atrial Fibrillation

  • Premature Ventricular Contraction

    Rhythm Irregular Rate The underlying rate P-wave Absent PR Interval N/A QRS complex Wide, abnormal morphology Table 1: ECG Characteristics [3] Clinical Significance [2] PVCs[] P Waves may be present or absent. P Waves are usually not seen if the rate is increased. If present, the P Waves have no relation to the QRS complexes of the V. Tach.[] P Waves may be present or absent. If present, they do not have a set relation to the QRS complexes.[]

  • Ventricular Tachycardia

    Answers Rhythm: Regular Rate: 150 P Wave: absent PR interval: n/a QRS: Wide and bizarre Interpretation: Ventricular Tachycardia[] Rhythm Regular Rate Fast (100-250 bpm) P Wave Absent PR Interval Not measurable QRS Wide ( 0.10 sec), bizarre appearance Notes[]

  • Corrected Transposition of the Great Vessels

    Electrocardiographic features that should suggest corrected transposition are atrioventricular block (particularly 2:1 or complete heart block), abnormal P waves, absent or[]

  • Cyanotic Congenital Heart Disease

    The electrocardiogram, in addition to any atrioventricular conduction disturbances, may show abnormal P waves; absent Q waves in V 6 ; abnormal Q waves in leads III, aVR,[]
